Store front construction



Feb. 8, 1938; I J. J. BOSSHARD STORE FRONT CONSTRUCTION Filed Aug. 17, 1936 VII/III/I/IIIIIIII Patented Feb. 8, 1938 UNITED STATES PATENT OFFICE STORE FRONT CONSTRUCTION Application August 17, 1936, Serial No. 96,371

Claims.

My invention relates to store front construction, and has particular reference to a construction in which a resilient mounting is provided for glass panes and the like, and which provides for a cer- 5 'tain amount of flexibility and resiliency for increasing wind strain and other shocks to which a glass may be subjected, thereby providing a structure in which breakage of the glass is less v liable to occur and which when the strain is removed allows the glass and mounting to assume their original position.

Another and further object of my invention is the provision of a store front construction in which glass of varying thicknesses may be mounted so that it is not necessary to provide special forms of mounting for varying thicknesses of glass. In my improved mounting, glass varying in thickness as much as a quarter of an inch may be used and mounted successfully without altering the parts or arranging them in a different manner whatsoever.

Another and further object of my invention is the provision of a store front construction in which a structure having a comparatively wide base is provided, by means of which the weight of the store front is supported inward from the edge of the frame or ornamental construction a sumcient distance so that the weight of the glass pane is adequately supported and undue strain is 30 not placed upon the structure, as is the case where heavy plate glass store fronts are placed adjacent the edge of the frame supporting structure or the edge of various forms of ornamental structures now commonly employed in store front construction. I

Another and further object of my invention is the provision of a store front construction in which a glass engaging member of rounded form is employed and in which the point of support is 40 adequate to hold the glass in proper position and yet allow the glass to flex or bend slightly under the influence of severe wind pressure or the like without danger of breakage or chipping off of the edge of the glass.

Another and further object of my invention is the provision of a store front construction in which a two-point support is provided at the outor side thereof for the outer glass pane engaging member of the store front construction.

These and other objects will be more fully and better understood by reference to the accompanying sheet of drawings, in which- Figure 1 is a cross sectional view through a section of a store front construction of my invention;

Figure 2 is a perspective View of a section of the outer glass engaging member; and

Figure 3 is a perspective View showing the inner glass engaging member, and the sill, in position to be applied to a window opening.

Referring now specifically to the drawing, and in which like reference characters refer to like parts throughout, a Window frame It] is shown of usual form, having a back portion II which extends upwardly from the'base portion. A casing member I2 is provided which is fitted against the base portion of the frame Ill and has a flange I3 at the rear side thereof angularly disposed with respect to the body of the member I2 and which is fitted against the back portion II of the frame I 0. A flange I4 is integrally formed with the casing member I2, which extends over the forward edge of the sill for protective and ornamental purposes, and may be in any form desired. 2

An inner glass pane engaging member is provided which consists of a base portion IS, a vertical wall portion I6, a web section I1, and a channel or glass engaging portion l8, all integrally formed, with the web section I! extending from the upper edge of the section I6 outwardly with the glass engaging portion I8 extending along the free edge thereof. The base I5 and rear wall portion I6 are in right angled relation with each other and are adapted to fit against the casing member I2 and the back wall portion I I of the frame III. A channel is formed on the outside corner of the juncture of the base portion I5 and wall portion I6, into which the flange I3 of the casing member I2 is fitted, thereby providing a substantially smooth outer contour for the casing member I2 and the inner glass pane engaging member which is interfitted into the window frame IO.

Extending longitudinally of the portion I5 is a V lar position of the flange portion 2|, is narrower at its inner portion than it is at the outer portion.

its normal position. This flange portion 23 is at substantially right angles to the vertical wall portion 25 and is adapted, to be fitted in full faceto face engaging position with the base of the casing member l2 when the flange section I?! on the inner glass engaging member and the rail section 24 on the outer glass engaging member are in substantial engagement with each other or spaced apart only a Very short distance, say of an inch. With the moving outward of the outer glass pane engaging member to accommodate a glass pane of varying thickness, the outer glass pane engaging member is therefore slightly inclined at an angular position, bringing the inner edge of the portion 26 of the outer glass pane engaging member against the under side of the flange 2! of the inner glass engaging member and at the same time the slightly angular position of the outer glass engaging member brings the corner between the vertical wall section 25 and the section 26 into firmengagement with the casing member I2 so'that in effect a two-point contact or engagement is provided for the outer glass pane engaging member at its outer corner thereof and along the inner edge of the portion 26.

The glass'pan engaging face 2'! of the rail 24 is slightly rounded so that regardless of the angular position of the outer glass pane engaging member a firm, wide contact is maintained with the glass pane 28 which is inserted between the face 2'! and the face of the flange member M3 on the inner glass pane engaging member. The rail portion 24 also has a slot 29 extending longitudinally thereof, within which the end of a spring member 20 is mounted, with suitable holes being provided in the end of the spring member 20 through which the metal of the rail section 24 is extruded at 3|, 3|, thereby holdingthe spring firmly in position in fixed spaced relation with other springs in the outer glass pane holding member when these sections are made at the factory. The spring 20 has an angularly disposed portion 32 intermediate its ends which is adapted to contact with the inclined surface of the portion I9, with an upturned inwardly extending free end 33, with which a screw-34, mounted in the web IT, is adapted to engage. When the screw 34 is tightened the outer glass pane engaging member is moved inward initially until firm engagement is established against the side of .the glass pane H and also between the inner edge of the portion 26 and the under side of the flange 2|, and also causes a firm engagement of the corner of the outer glass pane member upon the casing l2. Thereafter a further tightening of the screw 34 places the spring under tension, which in effect places the outer glass pane engaging member under tension as well as the spring holding the member in assembled relation and the glass pane 28 in proper position in the fixture.

Screws 35 are provided which extend through holes 36, 36 in the casing member l2 and in the base I5 of the inner glass pane engaging member, these holes 36 being normally placed in registering position with each other so that the inner glass pane engaging member is firmly secured to the window frame I0.

' In operation it will be understood that the casing'membe'r I2 and inner glass pane engaging member are placed in position in the frame [0, which has been prepared in form to receive them, and are secured to the window casing by means of the screws 33. In setting the glass, the outer pane engaging strip is placed in position, which has been preformed, and which also has the spring member 23 spotted in proper position so that when the member is placed in position the free ends of the spring member will come under the screws 34. After the glass pane is in position, the outer glass pane engaging member is tightened up by means of the screw 34 and in its initial movement the outer glass pane engaging member is drawn inward until the rail section is fairly taut against the glass pane. Thereafter the screw can be tightened, which puts the spring 20 under tension and in effect places the outer glass pane member under tension so that the whole construction is under tension to a certain extent. When it is desired to remove the glass, of course, the screws 3 can be loosened and the outer glass pane engaging member removed, allowing the glass pane '26 to be removed and replaced if desired.

While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form and the proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit or scope of my invention.
